President Donald Trump is racially insensitive and is working to reverse what the civil rights movement has accomplished, Rev. Al Sharpton argued in a new opinion piece.

In his story for NBC News, Sharpton argued that Trump contradicted himself when he signed a proclamation last Friday to announce Martin Luther King Jr. Day. A day earlier, Trump is alleged to have used the term "s***hole countries" during a discussion about Haiti and certain African nations.

"As his most recent comments about Haitian and African immigrants prove, Trump has no idea what it means to treat humans equally 'no matter the color or our skin,'" Sharpton wrote. "He also understands very little about the legacy of the man he claims to be honoring."

Sharpton then listed some of what King was able to accomplish during his life before his 1968 assassination.

"One of the biggest criticisms we hear about Trump is that he has spent his first year in office attempting to reverse President Barack Obama's policy achievements," Sharpton wrote. "While there is a lot of truth to that statement, it represents only half the story. In fact, Trump and his administration are undoing the progress that was achieved, not just by Obama, but by the civil rights movement.

"The White House has so far gone after health care, criminal justice reform measures, and environmental regulations while endorsing voter suppression tactics, flirting with nuclear disaster, and passing tax cuts that benefit corporations and the wealthy while indicating that they plan to target the social safety net next. Almost all of these maneuvers will directly impact communities of color; often, these types of measures impact communities of color the most."

Sharpton closed his story by noting, "We must remember the tremendous sacrifices of the civil rights movement, and ask ourselves: Are we truly giving our all? A situation this dire requires an equally impressive response. We must resist not only Trump, but also all those who would turn King's dream into a nightmare."
